4 Claims.

This invention relates to improvements in window and sash assemblies, and has particular reference to the conventional and slidable. double sash unit as mountedwithin a, suitable window frame provided with separate guide-ways for the outwardly positionedupper sash and the inwardly positioned lower sash. The present invention comprises certainM additions, modifications and improvements upon my co-pending application, Serial Number 531,137, filed April 15, 1944.

The primary` object of the invention is to provide, in a double sash window unit, the sashes being mounted thereinto slid'ably pass each other in the frame, a window. frame formed with outer guide-ways for the outer and upper sash and inner guide-ways for the inner and lower sash, the said outer guide-ways being inset relatively. to the inner guide-ways, or in other words positioned somewhat closer together, the usual medial parting strips beingcmitted, the outer guideways being thus defined by the lateral facing strips of theA frame and the outer stop strips thereof, and the inner guide-ways being defined by the lateral and more widely spaced facing strips of the frame thereat and by the resultant ledges providedvat each side of the frame by the relative insetting of the facing stripsdening the outer guide-ways as compared with the wider spacing of the facing strips dening the inner guide-ways, the usual inner guide-strips or stops being omitted, whereby both they lower sash and the lowered upper sash may be freely tilted in'- wardly and horizontally for cleaning, and then replaced to their normal operative positions in the frame.

Another object of the invention is to provide in a double sash window unit including a pair of sashes slidably mounted' in an oblong frame to slide by one another in opening or closing the same, said sashes being mounted in outer and inner guide-ways of the frame,l the medial parting strips of the frame being omitted and the inner sash guide-ways being widened relative to the outer sash guide-ways and the inner sash stop strips being also omitted, whereby the sashes may be tilted horizontally for cleaning, releasable means for normally holding the sashes to their operative position within their guide-ways,V said means comprising channels or grooves formed along the guide-ways, and elements movably secured to the side rails of the sashes and adapted to be protruded into or retracted from the said channels of the. guide-ways, the widened inner guide-ways forming ledges or abutments at eachl side of the frame for supporting the wider inner sash in position.

Still another object of the invention is to provide an oblong window frame having laterally spaced inner and outer sash guide-ways, the inner guide-ways being spaced apart somewhat at the` outer sidefof the frame to prevent the out-v ward displacement of the outer and narrower sash, chains or the like extended along through the saidchain-ways of the guide-ways, over pulleys at the topof the frame and weighted at their outer ends in conventional manner, the inner ends of the chains being disposed at the side rails of their respective sashes, means connecting these inner chain endsv with their sashes, and means utilizing the said chain-ways of the guideways for releasably holding the sashes to their normal operative position in the guide-ways, the conventional medial parting strips and inner stop or guide-strips of the frame being omitted, whereby the two sash in lowered position may be tilted freely and horizontally inward for cleaning and thereafter replaced to normal position.

With the aforesaid objects in view, together with such other objects and advantages as may appear from the specification, attention is directed to the accompanying drawing as illustrating certain preferred embodiments and structural features of the invention, and wherein:

Figure 1 is an inside elevation of a window frame and double sash unit as constructed in accordance with this invention, the sashes being shown as closed.

Figure 2 is a sectional detail on an enlarged scale, taken on the line 2-2 of Figure 1.

Figure 3 is a sectional detail on an enlarged sca-le, taken on the line 3-3 of Figure 1.

Figure 4 is a fragmentary sectional detail on an enlarged scale of the lower, right-hand corner portion of the assembly shown in Figure 1,

the sashes however being represented as lowered and tilted horizontally inward for cleaning.

Figure 5 is a detail View in perspective and on an enlarged scale of one of the follower or guide blocks for slidably mounting in the chain grooves or channels formed along the sash guide-ways of the window frame, and to which the sash chains or ropes are secured at each side of the sashes.

Figure 6 is a similar detail view in perspective, on an enlarged scale, of o-ne of the pivot attach. ment blocks, which are also slidably mounted in the chain channels of the frame and to which the lowerfends of the sash chains or ropes are secured at each side, these blocks in turn being pivotally secured to the lower ends of the side rails of the sashes.

and there being chain-ways Figure 'l is a view similar to that of Figure 1, the frame and sash structures being essentially the same, but certain modifications being embodied in respect of the sash chains and their accessories and method of mounting, and in respect of the means for releasably holding the sashes to their normal upright and operative positions in their guide-ways of the frame.

Figure 8 is a sectional detail on an enlarged scale, taken on the line 8--8 of Figure 7. Y

Figure 9 is a sectional detail on an enlarged scale, taken on the line 9-9 of Figure '7.

Figure is a fragmentary sectional detail on an enlarged scale of the lower, right hand corner portion of the assembly shown in Figure 1, the sashes however being shown as lowered and tilted horizontally inward for cleaning.

The drawing represents a window frame re-j ferred to generally at 5 in Figures 1 to 4, and at Ecrin Figures 'l to 10, the same being of the usual elongated and rectangular form, and including the sill pieces 6, 6a, side rails 1, 1a, seated upon the ends of the sill, and the upper cross pieces of the frame asindicated at 8, 8a, all of substantially conventional structure, with ,exceptions to be noted. Such frames are usually formed with vertically extended weight and chain wells or shafts 9, 9a, for accommodating, the sash weights II), lila and chains II, I Ia, of such assemblies, the said chains or ropes in lieuthereof being passed over pulleys I2, I2a, rotatably mounted within slots formed in conventionalv manner in the top corners of the frame. Conventionally the two sashes of such an assembly are slidably mounted within guide-ways of equal depth formed in the vertically positioned frame, said guide-ways being defined byvinner and outer guide-strips or stops and medial parting strips, all extended in parallely relation from top to bottom of theframe, at each side thereof and conventionally securedthereto.

D1n accordance with the present invention however, the inner and lower sash I4, Illa, is slightly wider-than the Vupper sash I5, I5a, and the inner guide-ways II5, 'I6cLa1'-`eV made correspondingly wider than the outer guide-ways I1, I'Ia, for slidably receiving the wider lower sash I4, the upper and outer sash I5, I5a, being similarly slidably mounted -within the vouterv guide-ways I1, I1a. This variance in the width ofthe guide-Ways may o fH course be accomplished in'any conventional manner, as by routing out the side membersfof the frame or by the addition of strips upon the outer margins or sides ofthe frame.A Thus lthere are provided at each side of the window frame, 'the ledges, shoulders or corners I 6b, Ic, for slidably supporting at its outer vertical corners the lower sash I4, Ida, andthusenabling dispensing with the usual medial parting strips at this point. In accordance with this invention the outer stops or guide-strips I9, I9a,r which denne the outer marginsof the outer guide-ways, are mounted permanently in place, for preventing the upper sash from falling outward, although this sash maybe lowered and tilted freely inward. Also it is obvious that the lower and inner sash may be freely tilted inward, due to the omission of the usual inner guide strips or stops.

In accordance with the invention the lower ends of the salient outer portions of the side rails 1, 1a, of the frame 5, 5a, from the corners or ledges lGb, I6c, outward, are cut away flush with the faces of the inner portions of the frame, as indicated at 1b, 1c (Figures 4 and 10), thus providing stops or abutments 1d, 1e, forl engaging the lower end of the lower sash. I4., 14a, when the sash is tilted inwardly and horizontally across the window sill, and thus supporting the sash in proper position for cleaning. In the present embodiments of the invention the usual chain grooves or channels as formed along the outer edges of the window sashes are dispensed with, and in lieu thereof rectangular chain channels or grooves 2e, Zea, are routed out or formed medially along in the side rails of the frame, medially of the inner and outer guide-ways I1, I1a, and the inner ends of the chains II, IIa, as passed over their pulleys I2, I2a, are trained along down through the channels 2D, 20, and are properly positioned alongside the side rails of the sashes.

In accordance with the invention and as illustrated in Figures l to 4, oblong'pivot and attachment blocks, or pivotal attachment blocks 2| are provided, the same being rectangular in form and adapted to seat within, nicely fill, and to slide freely along through the chain Achannels 20. These blocks are pierced at their lower ends with pivot pin holes 22 and at their upper ends withV chain'engaging holes 23, the upper margins of the holes 23 being split or parted as shown, for receiving 4a flat-chainlin-k. Pairs of these blocks are pivotally pinned by pins or screws 24 to the lower ends ofthe .sides of the sashes I4, I5, in transverse alignment. ThenV with the sash weights IB in proper ating the sashes in raising and lowering them, the inner ends vof* the chains'II are secured to the upper ends of the blocks 2I by passing a flat chain link down through the parted margin of each 'of the holes 23 .of the blocks, and then turning the linktransversely` within the hole; thus locking it in place, as indicated at 25 in Figure 4. Of course any othermethod as'd'esired, may be employed for securing the'chains to'thelblocks. The advantage of the described method lies in the fact that the chains may bereadily removed for repair, replacement or adjustment.

Similar oblong or guide blocks 26 are provided for'likewise slidably mounting withinthe'chain'channels 2) of the guide-ways 16,11. These" blocks `are formed with the' `medial andV vlongitudinally extended chain grooves 26a and are pierced .with spacedand in' teri'orly threaded bores 26b'upon` their inner margins as mounted in the chain channels. `Chain lock pins 21 are medially and rigidly seated within the grooves 26a, these pins being adapted to pass through any selected links `of vthe'sash chainsV II for holding the blocks xedly in any adjusted po-` sition upon the chains. These-adjustments are so made that with the sashes I4, I5 closed, and, the sash weights I0 properly elevated'for operating the sashes in the usual manner, then the blocks 26 as supported upon the chains within the chain channels 20, will depend sufiiciently below the upper endsof the sashes to allow suiicient clearances for the chains at the pulleys, as shown in the drawing (Figure 1) With the blocks 26 thus properly locatedm'upon thechains, with the chain grooves 26a turned inwardly towards the sashes, then oblong and thin latch plates 28 are mounted transversely over the grooved sides of the blocks by means of set screws 29 passed through the inner ends of the plates and into the bores 2Gb, said bores being formed upon the inner margins of the blocks for this purpose and so that the outer ends of the plates 28 may slidably overlie the outer margins of the chain channels 20, for holding these blocks properly in place, all as shown in Figure 3.

- ,Snap spring latches 30 are provided, each latch elevated position for oper-` and rectangular follower'blocksV comprising a pai-rior narrow and elongated leafv springs 33a', spaced apart at their outer ends and thereat secured edgewise upon a flat cross-piece 3Ilb. 'I'hese latches are secured to the latch plates- 28V by screws 3I- passed through the cross-piecesand into the outer ends of the plates. The free ends of the springs 33a are directed horizontally inward overv the plates 218', their inner ends being turned towards one another and their extremities then ared slightly asunder, as shown at 30e in Figure 3.

The sashes I4, I5, are .shallowly recessedl out upon their lateral edges in spaced relation to their upper ends corresponding to the downward spacing of the guide-blocks 26 as mounted as described upon the chains II, thus providing flattened recesses 3'2 positioned in exact lateral alignment With the guide blocks 26. These recesses 32 are extended straightly out through the outer corners of the sashes, and are thus adapted to smoothly receive and seat the complementary latch members 33 which are of thickness nicely to ll the said recesses. The latch members 33 are mounted in place in the recesses 32 by means of screws 34 passed through their base flanges and into the inner margins of the recesses, as shown in Figure 3. The latch members 33 are formed-with pointed or spear shaped heads 33a, which are aligned with and adapted to press in between the inner flared extremities of the springs 30a, when the sashes are forced outwardly in their guide-ways to their normal vertical position, thus releasably locking the sashes to their normal operative position in the frame. The described and complementary latch members are of course so formed and co-operatively mounted in place upon the sashes and frame respectively, that when the sashes are raised or pushed back to their normal vertical position and the latch parts are pressed together in intermeshed relation, the sashes will then be .supported by the latches snugly up against the outwardly positioned margins of their guide-ways and will be slidably held in place within their guide-ways by means of the guide-blocks 25 which nicely but slidably ll the chain channels I I in respect of their cross-sectional dimensions.

Thus in respect of the frame and sash assembly or unit as shown in Figures 1 to 6, and as just described, when it is desired to wash or clean the said sashes, all the operator need do is to lower them and then to pull their upper ends inwardly into the room, taking iirst the lower and inner sash I4 and lowering it horizontally, to which position it is held by virtue of the lower end of the sash abutting up under and against the stops 'Id of the frame while the body of the sash rests upon the sill 6, In this operation the sash pivots upon the pivot blocks 2I, as shown in Figure 4. Similarly the upper and outer sash I5 is then pulled out and laid down horizontally upon the lower sash I4 for cleaning. the sashes are returned to vertical position and scribed assembly. However the pivot blocks 2I and the guide-blocks 26 are omitted. In lieu 2I the inner ends of the sash set pull rods or bolts 26e are passed horizontally and' slidably through bores Mb, I5b, in the side rails of the sashes, the same being provided at their outer ends with axially extended pins 26d, the arrangement of these elements being such that with the said sashes positioned vertically in their guide-ways, in operative position, then the pins 26dv will enter the chain channels 20a at the inner sides of the chains IIa, and will nicely bear against the inner margins of the channels, as shown in Figure 9, thus preventing the sashes from falling inwardly. However, by merely pulling the bolts 26e inwardly against the action of -their springs, the pins 26d are withdrawn from the chain channels, and the sashes may then be readily pulled inwardly and lowered horizontally for cleaning, as in the first described arrangement.

If found necessary the'outer lower corner of the upper sash I5, I5a, may be rounded olf as indicated. at IEC, to prevent the otherwise angular corner from digging into and injuring the outer stops or guide-strips I9, 19a, of the window frame. Y

It is thoughtthat from the foregoing descriptions.. the construction. and mode of operation of thewindow and sash units Vof this invention will be readily understood, and while I have here shown andy described certain preferred embodiments of the units, and certain preferred structural:` features thereof, these said structural features may be changed or modified, within the scope however of the appended claims.
